udder problems-no milk in one side-blood in the other

Hi all,
We are new to goats and here's the scene. Our alpine/nubian mix had one super little female about a month ago. The doe has lopsided udders, with one side being easy to milk (we get 2-3 cups per day, with some blood) and the other side is super small and gives no milk. The kid hangs out with the mother, and we milk twice a day. Where should we start?
Thanks heaps to all,
Randy
